About These Units

About Square Gigameter

The square gigameter is a unit of area equal to the area of a square with sides of one gigameter (10^9 meters). It represents an enormous area comparable to planetary surfaces.

About Barn

The Barn is a slightly humorous unit of area used in nuclear physics. When atoms are bombarded with smaller particles such as electrons, the electrons are scattered as if the nucleus of the atom was a tiny solid object. The barn is used to express the apparent cross-sectional area of this scattering object. One barn is equal to 1E-28 square meters. Using this unit, physicists can say that such and such a nucleus is "as big as a barn", or 10 barns, or whatever. The proper SI unit to use for these measurements is the square femtometer (fm2); one barn equals 100 fm2.
